Quantum computers offer great promise in efficiently handling certain problems that are otherwise intractable on classical devices [1]}, [2]}, [3]}. Over the last two decades, the emerging field of quantum science and technologies has witnessed remarkable progress with applications spread across physics, chemistry, mathematics, biology, and finance [4]}, [5]}, [6]}. In particular, novel approaches to calculate ground state energies of quantum chemical systems, and which promise an exponential speed-up over classical devices, have made these class of problems a killer application of quantum computing (for example, see Ref. [7]}, [8]}, [9]}, [10]}).
